There are a couple of significant downsides that temper my enthusiasm for the new Gear. First and foremost is the speed and intuitiveness of the user interface - or rather, the lack thereof. There's a tangible lag to anything you do with the Gear, while the swipe gestures are hard to figure out and do different things depending on where you are in the menus.

Also important will be the Galaxy Gear's battery life. It does use the Bluetooth 4.0 Low Energy standard to communicate, but at 315mAh its battery is decidedly small. Samsung promises "about a day" of endurance from the Gear, but by the end of our briefing with the company, the cameras on most of its demo units were refusing to turn on due to the watches running low on power.

Samsung needs someone like Steve Jobs. Someone to actually use the device and has the power to order changes until it is something he or she would actually use. Who does this for Samsung?

I could see a watch with a one day battery life IF it was a full 24 hour day and recharging it meant dropping on a wireless charge pad when I took it off at night.

It also needs to provide something significantly better than pulling a smartphone out of my shirt pocket. I don't even wear a normal watch anymore because my phone is a perfectly decent pocket watch. Pretty much the only reason to wear a watch anymore is for the decoration which means it has to look good.
